To me, "utopiate" refers to a spiritual, inner utopia, an achievable one, as opposed to the external, idealistic political utopias usually discussed. But I guess I shouldn't surprise me that I'm not the first person to come up with that particular portmanteau.

Ideals can be perverted, idealists can go too far. Idealism is the utopiate of the apparatchik.--John Rodden, 2002, Repainting the Little Red Schoolhouse: A History of Eastern German Education, 1945-1995
